Hey i'm new here if you hadn't guessed. I've had my Anet a8 for a while now and I've been doing a couple of things but not with amazing quality. have been fiddling with the parameters but cant seem to get in any better. got any advice or can you see what is wrong straight away? any help would be appreciated.

here is my most recent print its a belt tensioner for the Y axis, thought it would help the quality but since the print isn't really the right shape i don't think it will work?

Pictures here, couldn't work out how to add them to the post sorry.
